3-Hydroxybenzeneboronic Acid Enables Stable and Sensitive Dopamine Detection by Inhibiting Target Self-Polymerization

Analytical Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: June 3, 2025

Resorcinol (Res) and Res-motif-containing molecules have been explored for the design construction of fluorometric probes toward dopamine (DA) detection. However, self-polymerization DA under alkaline conditions competes with probe-DA reaction, reducing stability sensitivity In this study, a target-triggered cascade reaction strategy has development detection probe based on formation borate ester intermediates. As case 3-hydroxybenzeneboronic acid (HBBA) was exploited stable sensitive by inhibiting self-polymerization. The mechanism study disclosed that first reacts HBBA forms ester, which is then oxidized hydroxylated to produce Res DA, further forming fluorescent azamonardine compounds. Using as probe, achieved limit 0.4 nM. addition, practical application verified accurate analysis in urine cerebrospinal fluid samples.
